Help with marks on an old brooch

[Tinkybell]

Hi all! I am new here and I found some marks on a brooch in my Gma's things. I can't make out two of them but one is a dogs head inside of a square ,with floppy ears. I would love to know where it was made or what it represents.It is gold(not sure what quality) on the back and silver on the front, with little chunks of diamonds. Any help would be appreciated.

Oh wow! That looks like the dog mark for sure. So that is the silver mark for it. I wonder if one of the other ones would be for gold? Thank you!

I can't make out the other mark. Do you have a loupe?

@AV_ is correct, I think. Hallmark is for a mixed metal piece though perhaps.

I am away from home on vacation this week. I can try and get a bit closer when I get home. I increased the size of the mark on my computer.
